To form the annular structure illustrated in Figure 2a the slitted portions Ia and 8a are folded in opposite directions over and adjacent to the unslitted portion 4a. It is irrelevant as to whether the slitted -portion 'Ila overlaps the slitted portion 8a or -vice versa, as it will neither affect the formation of the cake nor the wrapping of the same thereafter. This structure is then placed in the spinning bucket I0 in the same manner as the afore-described wrapper.

Although the wrapper may be placed in any type of spinning bucket, including those having a smooth inside wall, to form a liner therein, it has been found through actual practice that a bucket of the type illustrated in Figure 3 is the most satisfactory. This type bucket is substantially the same as the ones in common use except that the inside surface is iluted as shown by reference character II. The interior of the bucket is grooved parallel to the axis of rotation of the bucket to provide a better gripping action between the paper liner 2 and the bucket. Due to the centrifugal force created by the rapidly rotating spinning bucket, the paper is thrown against the wall of the bucket and conforms to the shape of the grooves which hold the liner tightly in place. The outside laps of the wrapper tend to form a cushion for the inside lap. There is sufficient serration on the inside lap to prevent slippage of the wound package, but not enough to damage any of the outer windings.

As shown in Figure 4 the paper or paper-like folded structure which acts as a liner for the cake is placed inside the bucket assembly prior to the formation of the cake and is substantially coextensive with the inside peripheral dimensions of the bucket. When the bucket starts rotating the funnel 9 reciprocates and feeds the filament 'I' into the bucket to form a cake therein. The folded liner-wrapper separates the cake from the surface of the bucket and thereby minimizes any damage that might occur to the outer rllaments of the cake.

When the formation of the cake I2 is completed and the rotation of the bucket ceases the dissipation of centrifugal force causes the cake to contract to its normal dimensions which simplifies its removal from the bucket, after which the wrapping is accomplished as illustrated in Figures 6, 7 and 8. As shown more particularly in Figure 6, the solid portion 4 surrounds the exterior of the cake I2 When the folded slitted portions 'I and 8 are protracted above the cake. When the slitted portion is pushed through the center of the cake at I3 it is of such a length that part of it extends below the bottom surface of the cake as shown in Figure 7. As illustrated in Figure 8, this slitted extension is then folded over the inside lap adjacent the cake so that it completely encases the cake and is held in place by the elastic band 6 and the slits on the tubular structure. The slits are expansible and provide resiliency in the wrapper thus forming a neat and compact package. Although the liner-wrapper depicted in Figure 2a has not been illustrated as to its method of wrapping it can readily be understood how it may be utilized. The slitted portions 'Ia and 8a, are extended to their full length at each end of the cake and folded into the center of the cake until they overlap.

The expansible and elastic permeable paper wrappers described have numerous advantages over the use of knitted wrappers in this invention. The greatest is that they are inexpensive and hence they may be disposed of after being used as a protective means for the wound lamentary packages during liquid treatment, vapor treatment, drying and the like and finally during transportation of the package to another plant for rewinding, throwing and other textile or preparatory operations.

By utilizing a cake lifter as shown in the patent to Pape 2,367,339 the actual handling of the cake prior to complete wrapping can be further minimized. At present there is an opportunity for the occurrence of great waste and damage to filaments as a result `of handling while removing the cake from the spinning bucket and wrapping it. If this ejector were used there would be no necessity to touch any of the filaments of the cake, thereby making a big saving in material.

While preferred embodiments have been shown herein, it is to be understood that the description is merely illustrative and thatmodications may be made without departing from the spirit and scope of the invention as defined by the appended claims.
